Hidden Power Indicator - Complete Explanation
Overview
The Hidden Power indicator is a sophisticated multi-timeframe trend and volatility analysis tool that combines:

Bollinger Bands (volatility measurement)

Keltner Channels (trend identification)

Linear Regression Slope (momentum detection)

Squeeze Detection (volatility contraction/expansion)

It helps traders identify:

Trend direction (bullish/bearish)

Momentum strength (via histogram colors)

Volatility squeeze conditions (potential breakout signals)

How It Works
1. Core Calculations
A) Bollinger Bands
Period: bolPrd (default: 20)

Deviation: bolDev (default: 2.0)

Calculation Types:

st_std (Standard Deviation)

st_ste (Standard Error)

st_sam (Sample-corrected deviation)

st_nos (Non-sample-corrected deviation)

B) Keltner Channels
Period: keltPrd (default: 20)

Spacing Factor: keltFactor (default: 1.5)

Uses ATR (Average True Range) for dynamic band width.

C) Linear Regression Slope
Period: LRPrd (default: 20)

Measures trend momentum (positive slope = bullish, negative slope = bearish).

2. Trend & Squeeze Logic
A) Trend Detection
Bullish Trend (trend=1):

When Bollinger Bands are inside Keltner Channels (low volatility).

Bearish Trend (trend=-1):

When Bollinger Bands are outside Keltner Channels (high volatility).

B) Momentum Strength (Histogram Colors)
Strong Bullish (lrhuu):

d[i] 0 (positive slope) & colors[i] == 1 (increasing momentum).

Weak Bullish (lrhud):

d[i] 0 but colors[i] == -1 (slowing momentum).

Strong Bearish (lrhdd):

d[i] 0 (negative slope) & colors[i] == -1 (increasing downward momentum).

Weak Bearish (lrhdu):

d[i] 0 but colors[i] == 1 (potential reversal).

C) Squeeze Detection
Squeeze (Up Arrow) (upK):

When trend[i] == 1 (Bollinger Bands inside Keltner Channels → low volatility).

Breakout (Down Arrow) (dnK):

When trend[i] == -1 (Bollinger Bands outside Keltner Channels → expansion).

Trading Signals
1. Buy Signals
Strong Bullish Histo (Green) → Momentum is increasing.

Squeeze Arrow (Up) → Expecting a bullish breakout.

2. Sell Signals
Strong Bearish Histo (Red) → Momentum is decreasing.

Breakout Arrow (Down) → Expecting a bearish move.

3. Weak Signals (Caution)
Weak Bullish (Orange) → Momentum may be fading.

Weak Bearish (Gray) → Potential reversal.

Alert System
The indicator can send real-time alerts for:

Histogram Color Changes (alertsOnHisto=true)

"Strong Buy" (Green appears)

"Weak Buy" (Orange appears)

"Strong Sell" (Red appears)

"Weak Sell" (Gray appears)

Squeeze/Breakout Alerts (alertsOnSqueeze=true)

"Squeeze" (Up Arrow) → Low volatility, expect breakout.

"Breaking Out" (Down Arrow) → High volatility, trend continuation.

Alert Types:
✅ Popup Messages
✅ Push Notifications
✅ Email Alerts
✅ Sound Alerts (alert2.wav)

Practical Use Cases
1. Trend Following
Trade in the direction of the histogram (Green = Long, Red = Short).

Use arrows to confirm entries (Squeeze = Prepare for breakout).

2. Mean Reversion
Fade weak signals (Orange/Gray) when price is at extreme Bollinger levels.

3. Breakout Trading
Enter when Squeeze Arrow (Up) appears, and price breaks Bollinger Bands.

Conclusion
The Hidden Power indicator is a powerful multi-purpose tool that combines:
✔ Trend identification (Bullish/Bearish)
✔ Momentum strength (Histogram colors)
✔ Volatility analysis (Squeeze detection)
✔ Multi-timeframe support
